2006 Chevy Cobalt ls 2.2 liter P2433 code
Ok. So I have had my cel on for quite some time now and decided it's time to get the yellow light out of my face. 
I am getting the P2433 code and have been researching the crap out of it but not having any luck. From what I understand it's sending out a high voltage signal to the ECM. It seems there is a Secondary Air Injection Sensor?? But when searching I am unable to find anything about a Secondary Air Injection Sensor. I'm thinking the sensor may be part of the check valve but not one hundred percent. Also could a crack in the line cause this code? (I don't think so but checking all ends.) If I need to replace the check valve then so be it but I don't want to spend $150 and that not being the issue. If anyone has ran into this problem before or has a solution it would GREATLY appreciated.
Thanks in advance!
